WowAce

Creates a search bar to search through a vendor's items.
You are now able to find much faster the item you want.

Please update to the last version (4.0) to enjoy a way better version of VendorSearch! (see changelog)

VendorSearch also allows you to filter the items in a vendor frame. You can choose to hide the things you can't wear, can't buy etc...

Depending on your settings, you will be able to see only the items corresponding to your search, or just hide by opacity-changing the items that are not corresponding to your search.

Since version 4.0, the interface has been completely enhanced to focus on what needs to be done : search.
It's now faster and more efficient than before. Please download version 4.0 now !
The dropdown menu is now gone, as users used 99% of the time the "by name" search.

Since version 1.98, the frame is refreshed with the right results when you change page.

Since version 1.9, you have more filters to precise your search : you can search by name, type, subtype, price <, price >, rarity. (see screenshots).

Since version 1.5, you can choose your own type of "hiding mode". If you want to see only what you're looking for, there is a "Full Hiding Mode", which just keeps what you want. For those who still want to see what the Merchant sells, but the results of the search at the same time, the "Opacity Hiding Mode" is perfect. It set the alpha of the non-result items a bit lower so the items you're looking for are like "highlighted".
